A simple data collection app for iPhones and iPads created for ranches with multiple rain gauges positioned around the property. The user enters the name of each gauge, which is then displayed in ascending alphabetic order. Upon selection of a gauge the user then enters the rainfall noted for that gauge, which is then presented in the order of most recent observation to earlier observations. Should the user wish to export data from this app, the iTunes File Sharing mode may be used to export SQLite files which may then be imported into an SQLite file reader or manipulator on the user's computer.
